Blue HV Battery Symbol 2007 Hybrid Escape
 

Something new. 2007 FEH that I have owned 6 years. Today the outside temp is around 44F. Noticed the NAV display is showing the hv battery symbol and front drive train symbol as blue, and each at times disconnected from other components. The hv battery charges to no more than 40% as indicated on a scagaugeII. No error codes are being displayed. Never noticed the battery symbol being blue before. Does anyone know what the problem is?
Thanks
